To all whom it may concern:

Be it known that I, CARL L. OLsnN, a citizen of the United States, residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Saw- Swages, of which the following is a specification.

My invention relates to saw swages and its object is to provide means of a strong and simple construction for adjusting the swage for the purpose of obtaining a greater or less degree of swaging action on the saw teeth or to adapt the anvil and die to teeth having different angles and at the same time to effect such end without decreasing the strength of the block in which the Operative parts are mounted.

To this end my invention is embodied in preferable form in the device hereinafter described and illustrated in the accompanying drawings.

In these drawings Figure 1 is a side view in elevation of the device showing the same applied to a saw; Fig. 2 a top plan view; Fig. 3 a longitudinal vertical section on the line 33 of Fig. 2; Fig. i a vertical section at right angles to Fig. 3 on the line l---fl of Fig. 3; Fig. 5 a detail plan of the anvil, as seen from the dotted line 5-5 in Figs. 3 and 4, the adjusting member therefor and the controlling member for said adjusting member arranged in the relative position which they are adapted to occupy on the swage block but detached from said block; Fig. 6 a perspective view of the parts shown in Fig. 5; Fig. 7 a detail view of the inner end of the controlling member, and Fig. 8 a detail of a swaged saw tooth.

Referring to the drawings, 1 is a saw to which is adapted to be rigidly secured by means of clamps 2, an arm 8 at one end of a frame or carrier l, the opposite end of which carrier or frame is provided with an arm 5 carrying a guide plate 6. Adjustably attached to the frame is a substantially cylindrical swage block 7 which is adjustable in a rotatable direction to permit the proper positioning of the die and anvil with respect to the tooth to be swaged. A guide ear 8 secured on the block takes over the edge of the frame. Clamping screws 9 extend through the frame and into the block on abling the block and frame to be rigidly clamped together after the desired adjustment has been obtained, elongated slots being provided in the frame to permit of such adjustment. By means of a screw bolt 1.0 which is screwed into the block and which has an operating lever 11, the block may be rotated with respect to the frame and saw to obtain the desired adjustment.

Extending transversely through the block is a swaging shaft 12 to one end of which is secured an operating lever 13. Intermediate the endsof this shaft there are formed on the surface thereof die faces let one of which is adapted to be forced against the lower side of a tooth to effect the swaging action.

Extending vertically entirely through the swage block is a screw hole and socket 153 having the upper portion thereof threaded to receive an anvil screw 16. Below this closing screw is adapted to be held the oblong anvil 17, the flat surface of one of the shorter faces of which is adapted to rest quarely against the upper edge of the saw tooth when the anvil has been adjusted to correct position for the swaging operation. This anvil has its greater length extending above the upper edge of the article to be swagcd. This anvil fits within and is cinbraced on three sides by the walls of a slot 18 out in the edge of a cylindrical sliding carrier bolt 19 which constitutes the adjusting member for the anvil. This bolt is mounted slidably in a socket extending sub stantially diametrically of the swage block and entering the anvil socket hole, and the bolt extends across the anvil socket. At the end opposite the slot 18 and on a portion of the periphery of the slide bolt opposite the said slot is formed a second vertical open slot 20 with which is adapted to engage a pin 21 projecting eccentrically from the end of a short cylindrical stud shaft 22 which is mounted in a socket extending from the outer face of the block into the socket provided for the slide bolt.

The stud 2-2 is provided on its outer end, outside the face of the block, with a suitable polygonal head 23, whereby it may be turned through the engagement of a suitable wrench. Surrounding the edge of the outer end of the socket in which this stud is mounted is a series of graduated numbers 24: with which is adapted to register a notch 25 cut in the head of the shaft. These numbers constitute an indicating scale by which the extent of movement desired to be given to the operating stud may be determined, for the purpose of regulating through the movement of said stud, the relative distance between the die and anvil. Set screws 26, 27, extend from the opposite faces of the block into the anvil socket 15, and their ends are adapted to be forced against the opposite flat sides of the anvil so as to hold the latv ter rigidly but adjustably in its socket.

A set screw 28, extends into the block from one face thereof and enters the socket of the slide bolt 19 and is adapted to bear against a flattened portion 29 of said. bolt for the purpose of locking the latter rigidly in place after it has been adjusted.

In the operation of the device the anvil set screw 27 is loosened, so as to leave the anvil free to move laterally,and then the set screw 28 is loosenedto release the adjusting slide bolt and the operating stud 22 is turned until the notch on its head registers with the number that corresponds to the particular shape of the tooth to be swaged and the depth of metal to be upset. The turning of the stud through the engagement of the eccentric pin with the slot 20 carries the slide bolt in or out, thus moving the anvil diametrically toward or away from the die, thus accommodating the space between the die and anvil to a less or greater acuteness of the point of the saw, and to obtain a less or greater degree of swaging action. The set screws 27 and 28 are then tightened and the anvil screw 16 adjusted so as to force the anvil downward in its socket to the proper distance from the die to admit the saw tooth. The saw is then clamped to the frame, the tooth to be swaged being admitted through the opening in the bottom of the block into the space between the die and anvil. The block is then adjusted by means of the operating lever 11 to clamp the lower flat face of the anvil squarely against the upper edge of the saw tooth. After the anvil has been set to the required adjustment the swaging handle 13 is turned so as to carry the die against the under face of the tooth, thus pressing the metal of the tooth against the anvil and swaging the tooth to the degree permitted by the distance between the die and anvil.

It will be seen that with my invention the strength of the cylindrical block is maintained substantially intact since the only part of the metal that is required to be cut away to accommodate the operative adjusting members is that necessary for the central anvil socket, the sliding bolt socket and the socket for the eccentric stud. The lateral adjustment of the anvil in connection with the positioning of the anvil with its reater lenoth extending vertically above the edge of the article to be swaged enables a considerable degree of adjustment to be obtained with a slight movement of the swaging block, thus obviating the necessity of having a large saw engaging slot in the block for the purpose of permitting adjustment through a long arc. By means of the projection of the headed operating stud locyond the face of the plug, such shaft may not only be readily operated by means of an ordinary wrench but also such projection serves in conjunction with the indicating scale on the face of the block to permit of the adjustment of the stud and of the anvil to any predetermined and desired degree without the necessity of cutting away the block so as to expose the'die and anvil to view. By limiting the adjustability of the parts to the anvil it is rendered possible to operate the die without danger of altering the adjustment by the rotation of the die during the swaging operation.

Having thus described my invention, what I claim is 1. In a swaging device, the combination with a block of a die rotatably mounted in said block, an anvil adjustable in a line parallel with its swaging face with respect to said die and positioned in said block to have its reater length at an angle'to and extending upwardly from the effective swaging face of the die, a sliding member in said block engaging said anvil, and means for adjusting said sliding member, substan tially as described.
